First we had the CHRISTMA EXEC, and now we have the DIR EXEC. Both have had a negative impact on the network. Fortunately, both have not been as serious as they had the potential. In both cases, explosive propagation has been done via NAMES files, but I know of no case in either where one of those NAMES files caused distribution over a major Listserv List. However, it is only a matter of time. While far from perfect, I would like to propose a method for slowing its distribution. I would propose a new postmaster command BLOCK. The syntax would be: BLOCK FN=filename filetype This filename filetype would be recorded, and any files to be distributed would be checked against this list. If found, the file should be held and a note sent to the postmaster. This is obviously a very rough proposal, which is why I've sent it to the list for further discussion, rather than directly to Eric and Turgut. Several questions I can see: - How to unblock a file(another command, or a syntactic option? - Are there other attributes to block against than filename filetype? - How would a postmaster say its ok to process this? - Should there be an option to search all spool files in the system to id those with fn-ft of block files. - Should it be extended from just postmasters to other users? Which others? List owners? Other postmasters from PEERS NAMES? Harry
